Tetrapod Zoology

Amphibians, reptiles, birds and mammals - living and extinct

  • A Need for News on Nototriton

    By Darren Naish | August 20, 2015 |

    I must have said that one of my aims here at Tet Zoo is to write about obscure amphibian species that rarely get covered elsewhere. The main thing stopping or slowing this plan concerns the availability of images – good, available pictures showing the species concerned are often not available. […]

  • Nobody Expects the Korean Crevice Salamander

    By Darren Naish | August 18, 2015 |

    Aren't plethodontids great? Clockwise from left: Northern dusky salamander ( Desmognathus fuscus ), one of many Desmognathus species within Plethodontinae; Red salamander ( Pseudotriton ruber ), a spelerpine; Four-toed salamander ( Hemidactylium scutatum ), the only extant member of its lineage (and hence sometimes given its own ‘subfamily’, Hemidactylinae).

  • Speculative Zoology Grand and Photoreal: Boulay and Steyer's Demain, les Animaux du Futur

    By Darren Naish | August 13, 2015 |

    Speculative Zoology has become a big draw here at Tet Zoo and I’ve now had reason to write about the subject on quite a few occasions (see links below). Today I’m writing about it again because a very interesting book wholly devoted to the subject has recently appeared: artist Marc Boulay and palaeontologist Sébastien Steyer’s Demain, les Animaux du Futur *.

  • Books of the TetZooniverse: of Paleoart, Bats, Primates and Crocodylians

    By Darren Naish | August 8, 2015 |

    Some of the books I need to review. They sit here on the shelves, taunting me. Every now and again I look at the huge number of books-awaiting-review that I’ve amassed, and despair. Reviewing books takes considerable time. Or, at least, it does when you think that it’s good practice to read the books before writing about them. […]

  • Horned Treefrogs and Other Marsupial Frogs

    By Darren Naish | August 2, 2015 |

    Today we’re going to look at one of the most remarkable groups of frogs in the world. And as of July 2015, there are over 6540 anuran species, so that’s a lot to choose from.

  • Surprises From Placental Mammal Phylogeny 2: Skunks Are Not Weasels

    By Darren Naish | July 25, 2015 |

    Time for another article on placental mammal phylogeny, again focusing on results that are still not tremendously well known outside the zoological community (for previous articles go here for a general introduction to placental phylogeny , and here for thoughts on the position of pangolins ).

  • Surprises from Placental Mammal Phylogeny 1: Pangolins Are Close Kin of Carnivorans

    By Darren Naish | July 21, 2015 |

    Illustration of an African Giant pangolin Smutsia gigantea , by John Wolf. Image in public domain. Further to the previous article on placental mammal phylogeny , I now want to start looking at a few specific details of the tree – details that are somewhat surprising in view of traditional ideas about the groups concerned.

  • The Refined, Fine-Tuned Placental Mammal Family Tree

    By Darren Naish | July 14, 2015 |

    The 'Novacek tree' - an influential view of placental phylogeny from 1992. Our understanding of phylogeny – the shape of the tree of life – is constantly evolving, and it’ll continue to evolve so for as long as new data keeps coming in and so long as we continue to generate hypotheses based on this data.

  • Goannas Dig the Deepest, Twistiest Burrows of All

    By Darren Naish | July 6, 2015 |

    A female Yellow-spotted monitor  Varanus panoptes  excavates what appears to be a shallow, decoy nest burrow after completing work at the spiralling burrow near her tail. Image courtesy of Colin McHenry, used with permission. Regular readers might remember the various coverage that monitor lizards, or varanids, have had here over recent months (see the list of links below). […]
